PARTITION PILASTER.

AppLication filed` .Tune 8, 1925. Serial No. 35,575.

My invention relates to pilasters for partitions in ofices, stores and similar-A spaces, and more particularly to pilasters of an ex,-v tensible type.

In an application filed by me4 on March 7th, 1925, Serial Number 13,711, I have shown a general type of' such pilasters and partitions characterized by the property of being held in place by pressurawithout the use of nails and screws for attaching the pilasters and partitions to either-.110er or ceiling, whereby the deformation of the floors and ceilings characterizing present day methods is entirely avoided, no marks being left when using my method in remove ing a, partition or in making changes therein. Besides disclosing the general principle of holdingpartitions in place by pressure,

I have shown in the aforesaid application a specific type of pilaster as one of theillustrations of my general method. My present invention is concerned withE another specific type of pilasters embodying the same general principle.

Inasmuch as these various types of extensible pilastersv lend themselves with equal readiness to the construction of partitions, I am. showing in the present case the structure of the pilaster alone, it being understood that various panels may be connected thereto either Vin the manner shown and y claimed in the above mentioned application Serial Number 13,711, or in any other suitable manner.

Referring to the drawings,Fig. 1 is a vertical section through a pilaster embodying by present type; Fig. 2 isa cross section along the line 2*2 of Fig. 1; Fig. 3 is the upper part of the pilaster shown in Figml, abutting on the ceiling, With ceiling strip and cross rail in position; Fig. 4 is a cross section through said ceiling strip and cross rail, away from the pilaster; Fig. 5 is a detail of the base of the pilaster; and Figs. 6 and 7 are details of a modiiication of my device.

Referring to the above figures more` in detail, my pilaster is composed of a main hollow post, 1, and an extension post 2, this extension post 2 being shown in Fig. 1 as elevated up to the ceiling 3. rlhe main hollow post 1 rests in a shoe 4 having sharp,- edged flanges or spikes 5 partly imbedded in the floor 6. Fitting into the main hollow post 1, at the base thereof, is a wooden block 7. Onv top of the block 7 lies a. metal base plate 8, to which is aixed in any suitable manner, such as, for instance', the screws 9, a vertically extending post 1Q. rIhis post 10 has a series of circurnferential flanges 11. The post 10 is truncated by,A two parallel planes along its entire length, thus causing the anges 11 to be interruptepli.4 A tube 12 surrounds the. post 10 andy is formed at its lower end into two partial o r interrupted, internal flangesgl?)` adapted to tit in between the flanges 11 of the post 10 for certain positions of the tube 12. The tube 12 is further provided with a collar 111, on whichrests a supporting plate 1,5, the1 latter ittingslidingly into the main hollow post 1 and acting also in the capacity of al guide. On the supporting y ings 16 for the tube 12, these` facings, 16, togetherk with` the tube 12, constituting the`v extension post 2. The tube 12 has ay plug 17 at its upper end. The plug 17 is perfo-I rated to permit the passage. of the threndedl stem 18y ofthe Urshaped member 19. A nut 2O on the stem 18, resting on a washer 21 interposed between said nut andthe plug 17, is provided with holes 22 adapted. to. receive a pin or lever` (not shown) for the purpose of turning` the nut. AV ceiling strip 23, trimmed to lit into the U-shaped member 19 so as to form a flush surface therewith, is braced underneath by a cross rail 24.-. A moulding 25 covers the face of the ceiling strip 23 and` apart of the cross rail On Fig. l1 is shown the manner of attaching glass or other panels to the pilaster extension` but as the manner of connecting panels to the pilaster does not formy a,y part of the present invention. no further notationsA are indicated.

In Fig. 5 is shown in cross sectionk the shoe l in which the main hollow post or the pilaster rests. The shoe is shown as enternal tothe pilaster facings. This shoe may be concealed inside the faci-ngsI of the pilaster by a slight and natural modification of design.

In Figs. 6 and 7 is shown a modification of the post 10. Instead of the :interrupted ianges 11 of post 10, We have here the in,- terrupted threads 11 on the post 10". It is found that sometimes it is easiery and cheaper to make interrupted ianges inv this plate 12,5,l rest fac-v sired height, for instance,

manner,

grooves 28 within which the fillers `27 fit tightly. Other nvertical grooves29 inthe facings 26 provide means tube 12. y

'The operation of my device needs but little-explanation. `Vhen the pilaster is un'- extended, then the entire portion which, in Fig.`1, is shown above the main hollow post 1, remains below the moulding (not shown) covering the upper `surface of the post 1 and ln this condition, the pilastermay be used for partitions which doe` not extend all the way to the ceiling.

When it is desired to extend the pilaster to the ceiling, one` would voperate as follows. The tube l2 is `given a quarter turn, to release the internal flange 13 from `engagement with the flange 11 on which it rested, whereupon the tub'ei12 is raised tothe deto the position Ushaped member 19 comes into close `contact with tlieceiling strip 2,3. The tube 12 is then given another quarter turn, which brings the flangel again into eni gagement withone of the flanges 11, thus securingthe tube 12 in its elevated position.

The adjustment is then completed as follows. The nut 20, which is preferably square, is turnedby 4means of a lever inserted in one of the holes 22, the result of such turning'being that the` `U-shaped member 19 moves upf ward. The Usliaped member 19 is prevented from turning with the nut 2O by the ceil` ing strip 23 which, it must be remembered, passes through atleast two U-shaped memy bers when a partition `is being erected. The

nut 2O is turned until the U-shaped member 19 exerts sufcient pressure ont-lie ceiling strip and, through theA ceiling strip, `on the ceiling. T lieaction of theinechanisin at the upper end of the pilaster vextension is comparable to thatl ofV a press.` After the tube 12`has thus been jacked up, the facings 16 are raisedup to the U-sliaped member, the cross rail Qd is placed in position, and the moulding 25 is nailed unto the ceiling strip, cross rail and facings 16. vThus the entire structure is firmly locked in position.
